Does a fuel system cleaner cause white smoke?

No, a fuel system cleaner, if applied correctly, does not creat smoke. A fuel system cleaner may combine with other impurities such as moisture, that become combustible when combines with a fuel sytem cleaner, and create white smoke.

White smoke is not caused by the fuel system cleaner, rather it is emitted when the fuel filled into the cylinder is not burning properly due to: petrol/water in the fuel, low engine compression,fuel starvation to the pump, and pump engine timing out. It's therefore important to establish the exact cause of the white smoke in order to stop it.

The white smoke is not from the cleaner. You have to look and see if you have a cracked head or blown head gasket. If the smoke smells sweet, you blew a head gasket and you'll have to replace it. If you try to drive it with the white smoke for to long, you'll blow the engine.

It may cause a white smoke while it cleans the engine but if it persists for a long time you may have another issue. White smoke typically indicates a coolant leak in the cylinder. Keep an eye on your coolant level to make sure that is not the cause.

I, too, had an oil change and they put fuel injector cleaner into my tank. The white smoke started coming out very badly, then it died down. I still see a little. The smoke was NOT coming out of my car prior to the fuel injector cleaner

Everyone always says its a bad head gasket, but white smoke was not present prior to the fuel injector cleaner. I have to believe there is a connection. Does anyone out there have information about the fuel injector cleaner. i don't have a blown head gasket! add a comment

I just added a bottle of injector/valve cleaner to diesel 2.5 Talbot express and I got plumes of white smoke for about an hour. Now it is ok. add a comment

Yes. Fuel system cleaners can cause white smoke. This is an improvement from blue smoke, which means that oil is burning. The cleaner probably got the oil out of a place in the engine where it was burning.

it should only smoke for about fifteen mins. usualy white smoke is common in the winter months this is on any vehicle and its not actually smoke its steam from the heated exhaust gasses. but if u are sure it is smoke then it should go away with ur next gas fill up.if not u have a biggar issue

The only thing that would cause white smoke would be if your engine was burning oil or some other substance. It usually will have nothing to do with a fuel system cleaner unless its dumped in the throttle body.
